Application gumm 3, 1916. Serial No. 107,437.

To all l/FIZOIIL 217 may concern:

Be it known that I, REUBEN B. BEN- 'aairx, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Humidifiers for Gas-Engines, of which the following is a full, clear, concise, and exact description,

reference being had to the accompanying drawing, forming a part of this specification.

My invention relates ,to humidifiers for gas eugi nes. In internal combustion engines it has been found that the combustion is im-' proved if moisture, in some form, is supplied to the combustion chamber. This supply of moisture also les'sensthe deposit ,of carbon and enables a lower grade of fuel to be used.

Among the objects of my. invention is to provide an improved device of the character imlicated which shall be simple of constru-ction and manufacture and eflicient in operation, and which can easily be applied to existing engines.

Further objects will appear from the de tailed description to follow and from the appended claims.

In the drawings, in which I have illus trated one embodiment of my invention- Figure l is a sectional view of the front part of an automobile;

Fig. 2 is a section on the line 2-2 of Fig. 3 is a section on the line 33 of Fig. 1; and

Fig. r is a section on the line' k-s of Fig. 2.

Referring to the drawing in detail the invention is shown in connection with an auto mobile of which the drawing shows the hood 10, the internal combustion engine 11, the radiator 12, the cooling water manifold 13 connecting the water jacket of the engine with the radiator, the carburetor 14, the

, dash15, and part of the frame 16. These parts may be of any suitable or standard construction. The radiator is provided with the lISlllll'OVtl'flOW pipe 17 which permits the escape of'steam and surplus water in the cooling system, and the carburetor is provided with the usual spray nozzle 18 and throttle valve 19.

For supplyin chamber a flexi. le conduit 20 is! provided vapor to the combustion Patented Oct. 8. 1918.

which isconnected to the fuel passage at 21 between the spray nozzle 18 and the throttle valve 19, and which extends up through the overflow pipe 17 to the space in the radiator above the top of the overflow pipe, which is usually located beneath the fi ing cap 22 of the radiator.

The flexible conduit 20 is considerably i smaller than the overflow pipe so that there is a passage 22 between the'outside of the conduit 20 and the inside of the pipe 17 through which the steam and surplus water may escape. For a'djustably support ng the conduit 20 with respect to the overflow pipe a collar 23 is threaded onto the conduit 20 and secured in the proper position by means of a set screw 24. This. collar 23 is recessed at 25 to provide passage 26 be tween the collar and the upper end of the overflow pipe for the escape of steam and water. To prevent water from splashing into the vapor conduit 20 or' from being poured into it when filling the radiator a check valve 27 is provided at the top of the conduit comprising a cup-shaped casing or cap 28 screwed onto the conduit, a .ball valve 25% and a coil spring 29 engaging the end of the conduit 20 for pressing the ball valve to its seat.

nor to the nipple 331m the ejector member. This e ector member is provided with a number of openings 34: disposed and arsis conduit 20 is connected in any suitable mang ranged so "that the flow through the fuel conduitwill cause'suction in theejector member and Will draw vapor through the conduit 20 from the space above the waterlevel of the radiator, the spring 29 yielding to permit the valve 28 to open.

On account of the connection of the vapor conduit to the fuel conduit being made between the throttle valve and the spray nozzle, the throttle valve will cause the ill vapor supply to vary in accordance with the fuel supplied (which it would not do. if connectedabove the" throttle) and still the air passing the spray nozzle will not be saturated by water vapor, as would be the case ifthe water vapor were supplied below the spray nozzle. By making the connection to the cooling system through the overflow pipe the necessity of making a special opening into the ,cooling system is avoided. By eating the ,fntrance opening of the vapor conduit iii he space above the water level in the radiator an ample supply of, water vapor is obtained as the Warm water rises and the vapor is quickly generated in this space.

The operation is as follows: When the engine is running water is forced through the manifold 13, radiator '12, and a water jacketfof the engine by any suitable means,-

not shown. At the same time suction in .the

- engine causes vapor tobe drawn in from the space above the water level in the radiator past the valve 28 through the conduit 20 and into the fuel passage 32 between the spray nozzle 18 and the throttle'valve19.

Having thus described my invention what I claim as new and desire ters Patent is I 1Q The combination with an internal combustion engine and a water cooling system therefor including a radiator having an overflow pipe for the escape of steam or surplus water of means for supplying moisture to the combustion chamber comprising a conduit in communication with the combustion chamber extending from the interior of said radiator through said overflow pip . 2.
